Another Newbie question....Alias

tetpt · 03-04-2005, 02:19 AM

I have a command I like to use a lot with a particular parameter and I would like to have it execute that way by just typing the command. I know I read this somewhere and it's pretty easy, but I forget how and I don't know where to look. What's the command?

hi there,

this depends of which shell you are using.
supposing bash, try

Code:

alias something="something --blah --blah"

then your command "something" will be executed automatic with the parameters --blah --blah.
you if want that forever, add this line to your .bashrc file.

if you do that, can you then use that command, with a different set of arguments? ie if you

Code:

alias shutdown=shutdown -h now

could you then

Code:

shutdown -r now

?? Just wondering

in that case u will need to write a shell script instead of just alias.

yep,

indeed and that is the danger to make everything an alias...
you could use sometrick like calling your first alias shutdown1 but this could bring a mess quite fast to your computer.
i agree with krishvij, write a small shell script and everything is solved keeping the feng-shui...

I guess I kind of answered that myself. Let's just say I want to take a look at the .bashrc file and make this change permanent, but I'm not quite sure where to look. If I use "find" I need to specify a path name. Is there a way to look if the absolute path is unknown?

Once I find this file, I can open it with a text editor and add the line at the bottom, correct? I think I'm going to try to work with emacs for now. Good start?
